Help.... she needs to know what her choices are! please!?

okay... say that there is a 14 year old girl and her parents have been divorced since she was 1. she lives with her mom and her moms husband, and he's lived with them for 10 years. she lives with them in Iowa. Her dad lives in Wisconsin with his girlfriend. the reason her mom and dad got divorced is because he has bipolar disorder and wouldn't take his meds, and was also an alchoholic. he beat her mom and her brother. she herself has now been diagnosed with bipolar along with afew other things, like adhd and insomnia, and before the doctors diagnosed her with bipolar they thought it was depression. she is doing well now, on bipolar, adhd, and insomnia meds. but thats only when shes not at her house, she is alot happier and does alot better with every part of her life if she is not at her house with her mom and "step-dad". when she is at her house she goes back to depression alot. she controls it better now by not harming herself, but she does not think its right that she feels this way

at her own house, she sees happy familys walking around all the time in her neighboorhood and cant think of a time that her life with her family has ever been that way. its not horrible emotional abuse at her house, but its pretty bad for her, since she already has all this stuff going on, and doesnt even remember the last time her mom said I love you to her. her step-dad makes her feel horrible, and her mom is like a whole other person when she's around people outside of the house and her husband, like shes afraid of him, and is hiding everything from everyone around her by putting on a smile

she's afraid if she stays at her house that something really bad will happen, she only feels scared at her house, she feels safer outside at midnight then she does at her house. her mom has been making her feel really guilty... by saying alot of things, like that she's fine with the fact that her dad beat the crap out of her mom, just because now that she's fourteen its not court ordered that she has to visit him, and her mom is scaring her, making her feel horrible, and she doesnt think that it will be ok to stay at her house, she doesnt think shes safe there, mostly, she doesnt feel safe from herself, because of how she feels at her house
the question is, what can she do? a 14 year old living in iowa, who doesnt think that she can live at her house anymore? does anyone know what her options are? like where she can go?
thankyou to anyone who answers!

her mom is saying abunch of bad things about her wanting to go to her fathers, saying things like that means its ok that he beat her since she wants to go visit him, also he still isnt exactly stable, may not be taking his meds, doesnt really have a job, hasn't paid alot of the child support, that kinda stuff, the last 2 or 3 girl friends he had left him, one may have been physically abused by him too. She doesnt know where she can go if not her dads and not her own house, if she stays at her own house she'll probably live, as long as she stays strong, i just dont think its right to feel that way in your own house, to feel just fine and good everywhere else but horrible and bad and like it would be better if you didnt exist at your own house....

OK to keep it short there are a number of things, a young persons place for people with mental health problems (been in one years ago) social services for rest bit care, her dads. all of them she will need to talk with her mother about. I think if she has contact with her dad it could be a good thing as he understands what its like to have bipolar (I have bipolar and my 7 year old daughter has bipolar and ADHD as well) maybe she could stay at friends every other night just till she feels better about being at home. She needs to see the doctor about how she is feeling as he may be able to help with all of this.
